Communication from React --> Unity Not Firing

[PaulineOC]

Hello! I'm so sorry to bother you, but I was wondering if I could get your help figuring out why my messages from React aren't reaching Unity?

In my React page, I try sending two messages to Unity in a React useEffect hook. The first one is the one I actually want (sending a string to my public Game Manager) and the other is a test, similar to the example implementation (with Spawn Enemies). Unfortunately, it never seems to fire/register in my Unity Debug Logs.

I ended up testing it as the example implementation, and it worked when firing from a button onClick, so I think it's due to the fact that my Unity scene has loaded / is on the first frame by the time I'm clicking the button.

Is there a listener for when the Unity build's awake function or is the best solution?

The Unity environment is 2020.3.30f1 and here is my package.json with all my modules;

Sorry I ended up figuring a workaround! Ended up setting a message from Unity to React when the start function fired and then fired the message from React to Unity
